Christian Nagel helped keep Earlybird running through the dotcom crash by investing the partners' own money, and he says the founders who stand out most aren't the "gritty" ones but the ones who learn and change fastest over just a few years. Outside investing, he's known as a world-class sailor who's won the Swan 45 world championship twice and once rode out a storm while windsurfing off the Skagerrak, and these days he also focuses on foodtech, talking in specific terms about things like precision nutrition, lab-grown proteins, and robotic kitchens.
